4. Thomas Jefferson National Accelerator Facility Page 4 UITF Progress meeting Action Items – November 23, 2015 Minutes New Action Items: Recall new dates: Facilities work complete August 2016, Poelker suggests we install new ¼ CM July 2016. MeV beam milestone pushed to September/October 2016. Is this OK with Team HDIce? Yes Can we wrap up UITF capital equipment project in FY16? Yes Downselect our means to cool HDIce: purchase dewars or connect to CTF Firm up the CTF shutdown schedule Poelker/Areti need to focus more attention on review processes and approvals: Operations and Safety Budget: ~ $55k capital equipment shortfall UITF and ~ $833k labor shortfall ITFCRY, ITFPTB and RSR

8. Thomas Jefferson National Accelerator Facility Page 8 UITF Progress meeting Status Facilities Precast concrete bids to arrive soon – this package includes bracing and means to secure 2 nd layer

9. Thomas Jefferson National Accelerator Facility Page 9 UITF Progress meeting Facilities Tasks and Timeline February 2016 Cave1 electrical work complete Facilities has issued PR for Cave2 concrete and bracing, out for bids March Installation Group willing to secure Cave2 structure, install other utilities April Facilities moves IPC outside Cave2 Concrete for Cave2 arriving on site, installing it Physics installs 2nd layer of concrete, adds bracing May Cave2 including labyrinth complete, roof not yet installed June Facilities focus shifts to utilities inside Cave2: electricity, lights, fire suppression, gate July Facilities continues to work on utilities inside Cave2: electricity, lights, fire suppression, gate August Facilities completes utilities inside Cave2: electricity, lights, fire suppression, gate, entire Cave2 roof installed. All bracing complete Facilities provides power to big Bertha from diesel generator (this could happen later, since no Beam to HDIce until Jan 2017)

10. Thomas Jefferson National Accelerator Facility Page 10 UITF Progress meeting Installed transfer line, leak checked OK Purchased a turbo pump for leaky shield line Building the heat exchanger Controls getting worked Status Cryo Group

12. Thomas Jefferson National Accelerator Facility Page 12 UITF Progress meeting Met with Cryo, SRF, RF, and Kazimi of Ops Discussing relief valves from ODH point of view Who does what? e.g. Cryo makes u-tubes and SRF stabs them, Cryo pulls cables, SRF provides connectors Expect 8 MeV beam with available klystrons Status New ¼ CM Test at CMTF June Install at UITF July

13. Thomas Jefferson National Accelerator Facility Page 13 UITF Progress meeting Cryo, SRF, RF and new 1/4 CM Recall, we agreed on means to “park” the ¼ CM when not accelerating beam: circulate 80K LN2 through 35K shield line. UITF should not be a burden on CTF 34 wks per year LN2 temp could fluctuate 80 to 100 K, no problem for parking but…. How to cool HDIce? I think we are leaning toward CTF connection… Nagging ODH assessment is “nagging” because some issues were ill-defined: parking strategy and relief valves New ¼ CM requires waveguide tuners Chad Seaton building the high power rf control board Next biggest issue: designing the waveguide layout

14. Thomas Jefferson National Accelerator Facility Page 14 UITF Progress meeting Gun HV power supply installed inside SF6 tank, very little corona at 60 psi Gun table and 80/20 keV beamline structure moved into place NEXT: add gun HV chamber, install big beamline elements, buy stuff….

17. Thomas Jefferson National Accelerator Facility Page 17 UITF Progress meeting Status Operations Network switcher hardware installed Computer terminals installed in control room 6100 IOCs ordered, but we can use older IOCs if needed sooner Groups are installing hardware in racks, and conversations have started with Software (Scott Higgins our POC)

18. Thomas Jefferson National Accelerator Facility Page 18 UITF Progress meeting Status Reviews UITF Accelerator Review: where beamline design is reviewed by Ops/CASA/SRF, March 15, 2016 Geoff Krafft, Mike Spata, Reza Kazimi, Arne Freyberger, Todd Satogata, Bob Rimmer Need to send out pre-review material soon: beamline design, optics envelope, machine protection Safety Systems Review, May 2016 Machine and Personnel, including radiation protection SCMB? UITF Readiness Review, August 2016 Commissioning and Operations plans Experimental Readiness Review, December 2016 Focused on HDIce Documents: FSAD, mini-AOD, ESAD

19. Thomas Jefferson National Accelerator Facility Page 19 UITF Progress meeting Status HDIce Stripline BPMs see 7nA beam with 1 Hz integration time. But we want to see 1nA beam, or even less at UITF. Don’t want to fly blind

20. Thomas Jefferson National Accelerator Facility Page 20 UITF Progress meeting Status HDIce Need to work out details with HDIce and T. Allison, J. Musson I peak I baseline Acceptable duration of high peak current: long enough to see but not long enough to depolarize

22. Thomas Jefferson National Accelerator Facility Page 22 UITF Progress meeting Budget Update: Getting into Target $55k UITF capital equipment shortfall, $833k labor shortfall ITFCRY, ITFPTB and RSR Engineering will donate money from one of their accounts to solve the UITF capital equipment shortfall of ~ 50k$. I believe this money will come from an account managed by Anthony Dipette. CEBAF won't suffer because we don't believe the work assigned to this account needs to get done this year. To help address the 833k$ labor shortfall in Accelerator NP accounts ITFCRY and ITFPTB, there are three possible paths forward: 1) Engineering will take a look at their ENGINF accounts to see if they can reduce scope and donate funds to Accelerator 2) Engineering staff who would normally charge RSR will work opportunistically on ITFCRY and ITFPTB when CEBAF does not require assistance. 3) Arne can reduce all RSR accounts by ~ 7% and we can assign this labor to ITFCRY and ITFPTB

23. Thomas Jefferson National Accelerator Facility Page 23 UITF Progress meetingBudget Gun Group procurements reduced by $55k to get capital into target, money moved to ITFPTB in defensible manner (yes, gun group will charge labor to UITFBL)

26. Thomas Jefferson National Accelerator Facility Page 26 UITF Progress meeting Budget ITFPTB

27. Thomas Jefferson National Accelerator Facility Page 27 UITF Progress meeting Schedule Ramifications Current status: Need to revisit Cryo costs, and especially costs related to connecting HDIce to CTF Fill the racks and start loading software – success will depend on groups working opportunistically on UITF ¼ CM – where the work of many groups converge…. Designer Shaun Gregory oversubscribed: moveable supports for “big” beamline items, waveguides, “songsheets”, stripline BPM can, chopper chamber, MeV beamline and 80/20 girder structure Gun Group tech support occupied at LERF GTS right now Have to get SCMB to weigh in on UITF shielding and means by which we limit beam current (e.g., PSS BCM(s)) RadCon: installing CARMS, is that a big job?

28. Thomas Jefferson National Accelerator Facility Page 28 UITF Progress meetingSummary There’s continued progress….

29. Thomas Jefferson National Accelerator Facility Page 29 UITF Progress meeting Backup Slides Backup slides from past meetings, P&C meetings

30. Thomas Jefferson National Accelerator Facility Page 30 UITF Progress meeting To refresh your memory… What we started with… UITF as imagined

31. Thomas Jefferson National Accelerator Facility Page 31 UITF Progress meeting Design work was stopped…would like it to continue

32. Thomas Jefferson National Accelerator Facility Page 32 UITF Progress meeting Status HDIce Lots of scattering at MeV energy. Beam size very large at target. Decided to flip the orientation of the target Cave2 design seems fine either way, need a Physics designer to be responsible for installation at UITF Target here Upstream radiation baffle blows up beam In this configuration, we can achieve desired small beam size at target Target here, better e-beam

35. Thomas Jefferson National Accelerator Facility Page 35 UITF Progress meeting Combine the two features that provided incremental success: shed and doped insulator Next test late September

36. Thomas Jefferson National Accelerator Facility Page 36 UITF Progress meeting The new gun happy at 325 kV, stopping at this voltage for now. Shifting focus to building the beamline and photocathode deposition chamber (LDRD magnetized beam tests) Building the electron gun at LERF GTS

37. Thomas Jefferson National Accelerator Facility Page 37 UITF Progress meeting Status SSG ODH system relatively simple: but need the power box removed from Cave2 PSS system more complicated: need Cave2 with a door, to install maglocks Henry thinks his group can do the work if CEBAF work doesn’t get in the way (Hall A ion chambers, Hall C in spring?)
